For the same reason that people aren't enslaved there.
Because you never know when a health care debate could turn into a slave auction.
Hmmm...I thought of this a while ago...
I helped my parents sell a litter of Corgi puppies over the summer. We got them sold for $350 a peice. Provided that this is a recession, I would say that the FMV in economically stable times is about $500. Now. Each Corgi puppy weighs 10 pounds and therefore sell for about $3-5 an once. This is roughly the old price for Silver when there was no hyper-inflation of metal prices. Therefore, it seems reasonable that a slave, with no physical (not fat,ugly or crippled) or mental(can do almost any task you need him/her to do) defects, should sell for the old price of gold, or $300-$500 an once ($5000 a pound, instead of $50/lb for the Corgis). Therefore, we can make a pricelist-
Slave Baby
$ 100,000
Slave Child
$ 250, 000
Slave Woman/sex slave
$1,000,000
Slave Man/eunuch to guard your sex slaves
$2,000,000
So yes....with me coming up with these prices, those rednecks are wise to arm themselves to the teeth...especially because I am not scared to "make" eunuchs.
